I bought a second-hand switch and after hardreset I installed it to my network with already installed ER605 and EAP660HD. Same day I started to get a alerts with TCP SYN packets attacks / WAN ping attack every 10minutes from different IP's. In meantime my public IP changed but attacks still happen so this gave me a idea that it's not random bot scanning IPs.Same day I started to notice weird issue with EAP660HD. Device keeps disconnecting and dropping client and provisioning again every time I use a speed test (so it's bandwidth related or whatever). There is nothing in logs about this shutdowns. I don't know that it's just a weird chain of coincidence/misconfiguration or serious problem. I know that this type of attacks are normal but for me it's very suspicious that attack start to happen same day when I installed switch and still persist after IP change.Someone can give me some advice?Thank in advance.
